Pastel (パステル - Pasuteru) is the deuteragonist in the Twinbee series. Pastel is Light's cousin and the pilot of Winbee. By all accounts, she's a bright and active girl. Like Light, she appears most often in cut-scenes, from which it would seem that she spends most her time on the beach. While on duty, she wears a pink and white costume with a large 'W' logo.

In Otomedius Excellent, she makes a cameo appearance in Donburi Islands piloting Winbee. However, Winbee takes a bad bump from running through a metal girder, causing its programming to malfunction and turn on the Angel pilots. Pastel pleads with Winbee to stop while it battles with the pilot, but when Winbee takes enough damage, Winbee reverts to its original programming and flies away with Pastel unharmed.
